Specification summary of EN 14592 as applied to wood construction screws (partially threaded): the dimensions the standard fixes, the full size range supplied, and the related designations commonly cross-referenced.
EN 14592 — Scope
The table below lists the dimensions catalogued for wood construction screws (partially threaded) under EN 14592. The scope of EN 14592 itself is not summarised here — where a figure matters, confirm it against the published document.
Tolerance & Product Grades
Product grade is a concept from dimensional fastener standards and does not apply to EN 14592. Tolerances for this part are the limits shown against each dimension in the table.
Dimensions Specified by EN 14592
| Nominal diameter (mm) | Head diameter dk (mm) | Drive | Thread length (mm) | Pilot hole in hardwood (mm) | Minimum edge distance (mm) | Common length range (mm) | Reference standard |
|---|---|---|---|---|---|---|---|
| 4.0 | 8.0 | TX20 | 40 | 2.5 | 20 | 40~80 | EN 14592 |
| 5.0 | 10.0 | TX25 | 50 | 3.0 | 25 | 50~120 | EN 14592 |
| 6.0 | 12.0 | TX30 | 60 | 3.5 | 30 | 60~180 | EN 14592 |
| 8.0 | 16.0 | TX40 | 80 | 5.0 | 40 | 80~300 | EN 14592 |
| 10.0 | 20.0 | TX50 | 100 | 6.0 | 50 | 120~400 | EN 14592 |
Equivalent Standards
Where direct equivalents exist (ISO ↔ DIN, ISO ↔ ASME), they are listed on the parent Wood Construction Screws (Partially Threaded) page.
Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.
Companion Standards
A complete specification for wood construction screws (partially threaded) normally cites several documents: one for the geometry, one for the material or mechanical properties, and one for the finish. EN 14592 is one of them, not all of them.
Custom manufacturing · Made to drawing
Need a screw to this standard in a non-standard size?
Parts built to EN 14592 are already in the catalog, so a special is usually a variation on existing tooling rather than a new design — which is what keeps the cost down. Made by cold heading or warm forging.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
